Production of high energy density in anti N-nucleus interactions

The results of an investigation of anti p- (and to a lesser extent) anti d- nucleus interactions are reported. The technique involves following the classical production and propagation of mesons (π,K+, K0, K-, K0, K*, eta, ω, phi) and baryons (N,Λ,Σ) in nuclei after antiparticle annihilation. It is found that small regions of the nucleus can be raised to sufficiently high energy densities that some predictions of a quark-gluon phase transition can be tested with the use of energetic antiprotons (5-10 GeV/c). the strangeness signal is examined and compared with the amount of strangeness produced in a recent experiment with 4 GeV/c incident antiprotons. A general expression is given for the total amount of strangeness produced which is invariant under intranuclear strangeness exchange reactions. 7 refs., 6 figs., 3 tabs
